CLOSURE FOR THE NECKS OF BOTTLES.

Specification of Letters Patent.

. Patented Sept. s, 1908.

Application filed January 25, 1908. Serial No. 412,574.

10 novel, simple details of construction for a closure for the neck of abottle or other receptacle, which when inserted and secured therein,after the receptacle is filled, will permit the contents to be freelydecanted, but will pre- 15 vent a refilling of the same.

The invention consists in the novel construction and combination ofparts, as is hereinafter describedand defined in the appended claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding arts in all the views.

Figure 1 is a sectiona side view of the up- 25 per portion of a bottleand neck thereon, and

a like view of the improved closure device inserted and secured in thepouring end of the bottle neck; Fig. 2 is an exterior side view of theim roved closure, and of the portion of the nec of a bottle engagedtherewith, seen opposite the arrow 00 in Fig. 1; Fig. 3 is a transversesectional view substantially on the line 33 in Fig. 1, and Fig. 4 is asectional side view of a bottle neck and the improvement securedtherein, these parts being inclined so as to dispose them in a positionfor discharging the contents of the bottle.

In the drawings, 5 indicates the body and 6 the neck of a receptacle,that may be formed of any suitable material and have any referreddimensions. The neck 6 of the bottle body 5, shown to illustrate the aplication of the improvement, is cylindrical and at the end furthestfrom the body, is internally threaded, as shown at a, in Figs. 1 and 4,said thread being of a coarse pitch.

The improved closure for the bottle neck 6, is in the form of asubstantially cylindrical plug 7, which together with the body 5 andneck 6, is preferably made of glass, cast or blown into shape. Anexterior thread a, of coarse pitch similar to that of the interiorthread a, is formed u on one end of the closing plug 7 and exten s fromthe extremity b of said plug to a collar 8, which projectscircumferentially therefrom at a proper distance from said extremity.The exterior dia and a, which will im inge the true end of the neck 6upon the co ar 8, as shown in the drawings.

Centrally in the end of the closing plug 7, that has a screwedengagement with the neck 6, a cup-like recess a is formed of a suitablede th and terminates at a concave bottom wall (1. Extending from therecess 0, at. the side wall thereof, a narrow channel e is formed in thebody of the closing plug 7, and terminates a short distance below the towall g of said plug, and thence extends I; through the same, thusaffording a continuterally ous passage 6 for air or liquid from thebottle .bod 5, outwardly. As shown, the passage .or c annel e may bewidened in a plane parallel with the top wall 9, and thus afford-5;

greater freedom for the exit of fluid there-;

through.

In the body of the closing plug 7, between the concave bottom wall (1 ofthe recess a and the outer end wall g, a curved and laterally disposedcavity i, is formed, which extends from the longitudinal channel etoward the opposite side of the plug. The laterally extended cavity 2'which is near the outlet 6, from its end that is furthest from thechannel e, is reduced in size and extends through the side of theclosing plug, as shown at 71, thus affording a duct for air or liquidacross the plug. Opposite, shallow recesses 'm are formed in theinternal and external threads a, a, at different points, two of suchpairs of recesses m appearing in Figs. 1 and 4 of the drawings and ineach pair of these recesses, a spring dog a is located, one end of thedog that is in the form of a thin strip of resilient metal beingembedded in the thread on the plug 7, the free end thereof being adaptedto enter the mating op osite recess, and interlock with an end Wallthereof when the plug is fully screwed into the neck 6. The receptacle5, before insertion of the closin lug 7, is filled with the liquid orother mo i e material it is to hold, and then is closed by screwin theclosing plug into the neck 6, until the co lar 8 is seated upon the trueend of said neck, as shown in Figs. 1 and 4 of the drawings. U on acomplete insertion of the closing p ug 7, the spring dogs n willinterlock at their free ends with the end walls of the recesses m andthus prevent the plug poured therefrom by inclining the bottle so thatthe neck 6 will assume the position shown in Fig. 4, thus disposing theopening 1', downward for the escape of the contents of the bottletherethrough, the lateral passage 6'' becoming an inlet passage for airthat flows through the channel 6 into the recess a and thence into thebottle body, which facilitates the free discharge of the liquidtherefrom, the liquid at the same time traversing the channel in anopposite direction to enter the duct 1).

It will be obvious that it will not be possible to readily fill thebottle after its contents have been removed, as there being but onenarrow channel thereinto throu h the plug 7, air cannot freely escapeupwardly and the liquid pass down therein at the same time.

Having thus. described my invention, I

claim as new and desire to secure by Letters Patent,

1-. A closing plug for the neck of a receptaole, comprising acylindrical body having an external thread at one end, said end having abeing cupped recess therein, the plug also having a longitudinal channelextended from the recess to a point near the outer end thereof andthence laterally through the side of the plug, and further provided witha transversely disposed duct near said outer end, that extends from thelongitudinal channel through the opposite side of the plug.

2'. A closing plug for the neck of a receptacle, comprising acylindrical body, a radial collar thereon near one end, an externalthread on said end, the body having a cuplike recess, therein at. thethreaded end, also a longitudinal channel extending from the recess atone side thereof to a point near the opposite end of the lug and thence.laterally out through the si e of the plug, the latter further providedwith a transverse duct that extends from the longitudinal channel outthrough the opposite side of the plug, and a spring dog embedded in arecess formed. in the threaded end portion of the p 1% testimony whereofI have signed my name to this specification in the presence of twosubscribing witnesses.
